WILLIAM FARHAN, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR OF TWO-THIRDS TO JAMES F. VALENTINE, OF WOODLYN, PENNSYLVANIA.

CARPET-CLEANING MACHINE.

Specification of Letters Patent.

Patented Jan. 14:, 1908.

To all whom it may concern.

Be it known that I, WILLLIAM FARMAN, of Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Carpet-Cleaning Machines, whereof the following is a specification, reference being had to the accompanying drawings.

It is the object of my invention to provide convenient mechanism for cleaning carpets by subjecting them to a beating and brushing operation, and also to an air blast, for the purpose of blowing out the dust which has been loosened by the beater.

My invention relates to a machine in which the parts are so arranged as to be reversible in their operation, so that a carpet may be passed through the machine in one direction and by a proper reversal of the mechanism it can be drawn back through the machine to the point where it originally entered and reintroduced without the necessity of either manual labor or special carrying devices to transport it from the back to the front of the machine.

My invention also comprises certain other novel details and combinations of cleaning apparatus which will be fully explained in the specification and pointed out in the claims which follow it In the accompanying drawings, Figure I, is a plan view of a machine conveniently embodying my im rovements. Fig. II, is an end elevation 0' said machine. Fig. III, is a fragmentary elevational view as seen from the right hand of Fig. II.

The entire mechanism is mounted in a housing formed by the wooden uprights 1, 2, and 3, joined by suitably disposed cross pieces and braced by the diagonal supports 6, 7, and 8.

The main shaft 10, is provided with the driving pulley 11, and carries the loose pulleys 12, and 13, arranged to be connected therewith by the clutch mechanism 15, which is controlled by the lever 16. Said pulleys 12, and 13, are connected to the pulleys 18, and 19, on the worm shaft 20, by the straight and crossed belts 21, and 22, respectively.

The worm shaft 20, carries the worm 24, in mesh with the worm gear 25, on the shaft of the driving roller 26, which is geared to the opposed driving roller 27. Between said rollers the carpet 30, is progressed in a direction dependent upon their direction of rotation, which, as may be readily seen in Fig. II, is dependent upon the position of the clutch 15.

The carpet 30, is conveniently supported while being progressed through the machine beneath the beating mechanism, by the straps 32, which extend longitudinally with respect .to the direction of travel of the carpet, and, are supported by cross ieces which extend transversely thereto, an said carpet is guided through the brushing and blowing .mechanism, between the guide wires 33,

and 34, respectively above and below, which also extend longitudinally with respect to its direction of travel.

The beating mechanism comprises a drum 35, having a number of parallel beating straps 36, preferably of leather, attached thereto, whose free ends are arranged to strike upon the upper surface of the carpet 30, between adjacent supporting strips 32, (see Fig. I). Said straps 36, are arranged in groups of six, each group being attached to a rod 38, which is pivoted in eyes 39, projecting from the periphery ofthe drum 35, and, so arranged that the groups of straps will be circumferentially disposed equidistantly in staggered relation with each other. Said drum is connected by the belt 40, with the counter-shaft 41, which carries the 42, and 43, connected by the straig t and crossed belts 44, and 45, respectively, with the direct and reverse loose pulleys 46, and 47, having a reversing clutch 48, interposed between them and operated by the hand lever 49, the handle of which conveniently exulleys' tends to the frontof the machine convenient to the operator. Accordingly, the shaft 41, is driven in one or the other direction as the lever 49, is shifted by the operator. The shaft 50, which carries the pulleys 46, and 47,

is provided with the pulley 52, which is conwires 34, with their bristles sweeping up be.

tween said wires, and the brush 62, disposed above the guiding wires 33. The brushes 60, and 61, are driven by belts 64, and 65, re-

. spectively from pulleys 68, and 69, on a short auxiliary shaft 70, which is driven by the belt 71, from the main shaft 10.

The brush 62, is conveniently journaled in vertically disposed reciprocatory slide bars 75, so disposed that it brushes the upper surface of the carpet intermediate of the lower brushes 60, and 61, which brush its lower surface, and by the shifting of said slidebars, the pressure of the carpet upon the brushes 60, and 61, may be varied accordingto the vertical position of the upper brush 62,.which is connected by the belt 76, to the pulley 77, whose short shaft 78, is journaled in one of said slide bars and carries the pulley 79, connected by the belt 80, to the pulley 81, on the shaft 41. Slide bars 75, are braced by the rod 74, which extends across the machine and is located, as indicated in dotted lines in Fig. II, so that it will not interfere with the belts 44, and 45.

The vertical position of the slide bars, and accordingly, of the shaft 78, and brush roll 62, is regulated by a hand lever 82, which extends to the front of the machine, and which operates the rock shaft 88, provided with two arms 84, which are respectively pivoted to the opposite slide bars 75. The position of said lever 82, is regulated by a detent 85, carried thereby, which engages the sector 86, by means of which it may be retained in a position to either elevate the brush, to prevent its contact with the carpet or depress it into any desired degree of pressure upon said carpet.

The blowing mechansim comprises the pipes 87, and 88, respectively above and below the path of the carpet. Both of these pipes are fitted with connections leading to a source of compressed air, and perforated at suitable intervals toward the faces of the carpet in order that a series of air blasts may be directed upon the carpet, to blow out the dust which has been loosened by the beater and brushes. These pipes are arranged for a slight reciprocatory motion in order that the air jets may be directed upon every portion of the carpet and for this purpose the pipe 87, is suspended by the pivoted links 90, and the pipe 88, is supported upon the pivoted links 91. Said pipes .87, and 88, are connected by arms 92, and 93, with respective eccentrics 95, and 96, which are mounted u on the main shaft 10, and by the rotation of these eccentrics said pipes are given that reciprocatory motlon above described.

respect to Fig. II, and is progressed there through in the direction of the arrow inclicated in said figure, the rotary parts rotating in the direction of the arrows marked thereon, (preferably that direction in which the carpet is passing through the machine). At the same time, the extent of pressure upon the carpet by the brush 62, may be varied by the hand lever 82.

hen the latter end of the carpet has reached the feed rolls, their direction ofrotation may be reversed by shifting the lever 16, andif desired, the beater drum 35, and the upper brushing roll 62, may be reversed by the hand lever 49, and in this way the carpet'will be subjected to the action of the renovating devices as it is progressed in either direction through the machine. This reversing operation may be repeated as often as desired, and with a greater saving of labor as compared with machines in which, after the carpet has passed. completely through it must be carried to the front of the machine and again fed through in the same direction.

It will be observed that the capacity of the beater to operate in both directions, is greatly dependent upon the flexible character of the beating straps 36, and of the nature of their connection with the drum.

I do not desire to limit myself to the pre- 'cise details of construction and arrangement herein set forth, as it is obvious that various modifications may be made therein without departing from the essential features of my invention.

Having thus described my invention, I claim 1. In a carpet cleaning machine, the combination with a beater drum of means for supporting the carpet during its progression through the machine; feed rollers below said supporting means; a brushing roll, supported above and in proximity to the path of the carpet; means for simultaneously reversing the direction of rotation of said beater drum and brushing roll; and independent means for reversing the direction of rotation of said feed-rolls, substantially as set forth.

2. In a carpet cleaning machine, the combination of a support for the carpet; brushes below said support; a brush mounted above said support in vertically reciprocatory slide bars; means for driving said brushes; and a hand lever operatively related to said slide bars, whereby the position of the upper brush roll may be varied.

3. In a carpet cleaning machine, the combination of a support formed by guiding wires; brushes below said wires; a brush mounted above the wires in vertically reciprocatory slide bars; a rock shaft; a hand It may be noted that the carpet is first 1 lever secured to said rock shaft means confed into the machine from the left with l necting said rock shaft with said slide bars;
